15 tips in Photoshop actions / batch

1. To play only one step in an action, you can choose the steps and press Ctrl click on the "Play" button, below the floating panel in the "action" play the selected action. " (Window> Actions)

Note: To change the parameters of a specific command steps, just double-click this step, showing that the relevant dialog box: the new value of any input will automatically be recorded.

2. To return to the playback from a specified steps, only need to select the steps need to start playing, and then click on the "action" floating panel below the "Play the selected action" button.

3. If you record an action may be used for different size of the canvas, then please send your ruler units into percentage. This ensures that all commands and brush strokes to the canvas size of the record - rather than on specific pixel coordinates.

Tip: To quickly change the ruler units, just right click on the "ruler" [Ctrl + R] (View> Rulers), then choose the unit of measurement you need. You can also access the ruler settings by double-clicking the ruler, or Edit> Preferences> Units & Rulers "menu, the [Ctrl + K, Ctrl +5] Gateway EC5802U Keyboard.

4. When you record or edit an action, you can insert a menu command, only need to select the Insert menu item can be in the "action" floating panel.

Tips: For step generic record in the action, which is a good way, for example, the menu command through the default parameters without being recorded.

5. Press "CTRL + ALT" and "action" floating panel, select Storage action on all the action can be saved as a text file. This is useful when you review or print the contents of an action.

Note: This text file can not be re-loaded into Photoshop's.

6. Action, it has a really powerful feature is that it can play other action, even in the fixed action set. Contains the part of those able to split to the action "subroutine" repeated command, this feature is ideal because it can make the action easier to edit and maintain. When you record an action when the other action and click "Play" button, the Play command will be as an action step is recorded to the current action.

7. Use the File> Automatic> Create Droplet command an action can be saved as a droplet. A droplet is a small executable file, open it to automatically open Photoshop and designed action applied to anything you drag it to the image above.

8. If you default in Photoshop "action" folder, create subfolders to manage your actions, Photoshop can still find these actions, or even floating in the "action" panel, so that they are available.

Note: The action of the sub-folders, or independent action, they will be able to disable the use of a "~" symbol.

9. If you are not satisfied with the results after you run an action, you must revoke all the steps in this action. In fact, do not only need to run an action before the floating panel in the "History" click "to create a new snapshot to create a snapshot, so you can click on the snapshot to restore the image state before the action execution.

Tips: ImageReady in its "History" panel in action as a single step, you can revoke these actions through a step.

10. Press the "Alt" key (Gateway EC5809U Keyboard) "action" action steps to drag the floating panel will be able to copy it.

11. To create a path that contains an action is necessary before you record this action to create a path, then this path is selected, start recording and floating in the "action" panel, select "Insert path.

12. You can use the "Shift" key to select a continuous action steps, use the "Ctrl" key (Gateway NV7921U Keyboard) to the non-continuous action steps included in the range of options. Then you can move, copy, delete, or even play the selected steps.

Note: you can only select the multiple steps in one action.

Batch processing techniques

13. To improve the batch performance (File> Automatic batch processing), can open the "Edit> Preferences> General, and to reduce the number of historical records state, and then find the" History option in the "history" floating panel menu Tick ??removal of the click in the window that opens will automatically create a snapshot first.

14. In a single batch processing of multiple folders, you will need in the Tick "Include all subfolders, create a shortcut to the folder in the source folder for all files you want to deal with.

15. You want to batch multiple actions, you need to create a new action, and record each action you want to deal with in this batch, then use the newly created action to run the first batch.

Tips: This method can also be used in the above 14 tips.

Failure often appear in the top five notebook

Electromagnetic interference

Better quality desktop chassis, to mask their own and external electromagnetic interference, so the work does not interfere with external electronic devices when not vulnerable to other electromagnetic interference. In contrast notebook computer becomes "thin" and more, is not the same as desktop hard shell, although the advanced circuit design and manufacturing processes so that she can not interfere with external devices, but can not avoid foreign "invaders ": from external electromagnetic interference. Daily work of the most common source of interference is a mobile phone if the phone is placed on top of the laptop is in operation, it is easy to make calls when the computer crashes, or automatically shut down, so be careful not to put the phone on top of the laptop is running , especially the keyboard parts.

Keyboard water

Body structure in the notebook computer, the keyboard is the most prone to water things, keyboard water, due to the keyboard is a keyboard passive (no power supply), part of the circuit will not cause direct damage, but the keyboard is easy to cause internal The role of the printed circuit conductive so bad to lose the keyboard failure scrapped, then it can only replace the keyboard, so when in daily use must be taken to prevent such occurrences. If that water, Gateway M-6755 Keyboard failure, Luo little trouble, the best computer service center or contact it.

Heat

Laptop cooling manufacturers have been very important issue, whether active or passive thermal heat dissipation, heat transfer are required to rely on air circulation, manufacturers use various forms of active cooling technology will be in the body of a notebook computer leaving some air circulation holes, some of these holes in the fuselage side, and some below, a little observation will find them. Thanks to the stable operation of the computer on which the most important thing is to not block the ventilation holes. As the laptop body is small, easy to carry, we will always hold it do not pay attention on something soft, such as their legs, bed, sofa, which blocked cooling holes, and over time, using will feel hot, even when the machines. Therefore, in daily use for more than a little to avoid the scenarios can solve this problem.

LCD screen

LCD screen of the most vulnerable components, and because of its thin glass structure, it is easily broken by external force, of course, users do not intentionally throw touch, but likely to close my notebook and put some heavy objects on top, so that accidental damage to the screen, generally in the notebook manufacturers packaging clearly indicate the site of a laptop can withstand gravity.

In addition, the notebook LCD screen surface of the plastic layer is also easily scratched by hard objects, resulting in scratches can not be eliminated, should be to avoid such occurrences. LCD screen of the daily cleaning need not be too cautious, with a soft cloth on it, the LCD screen itself has a certain hardness, so do not worry about rubbing bad.

Hot

Hot-plug should be absolutely prohibited. Unless otherwise specified, can be hot-pluggable. Especially in serial and parallel port, the computer is easy to operate when the hot-house integrated circuit breakdown, laptop for easy mobility makes it easier to shut down and then connect to other devices too lazy to worry damaged interface, so it should be absolutely avoid the surrounding hot.

The above five points, including a notebook computer using the most easily overlooked when the common problems, including electromagnetic interference, Gateway M-6755 Keyboard water, heat vents, LCD screen, hot-swappable. Believe that using a laptop would be of great help to the users, take note of these conditions will significantly reduce the failure rate of machine Oh.

Use the spacebar keyboard skills

Spacebar on the keyboard is operating the computer users who will be used. But its use may not know all. Here I will introduce a variety of uses under the space bar?

1. Perform a shadow option. General software program interface will have an option to cover the light shading, if the item is selected, the space key role is to check / remove the check; if it is the "Next" "OK" and other options, the space bar The role of the left mouse button or the Enter key equivalent.

2. Filling do not want to fill the position. Such as Tencent QQ, if you do not want to fill in names such as age, occupation Province City complex options, chaos filled can of course, but by a space bar is undoubtedly the most easy way to go.

3. Turn the page. In browsing the web, click the space bar is next to a page, the same role with the PageDown key (Acer Aspire 1640Z Keyboard), especially when read novels online convenience.

4. The pause / play. In many key players in the space are useful, most of the control the pause / play, such as Mpc and KMPlayer, press the space bar with the mouse to point over that little pause / play button faster.

5. Game button. In the game, the role of the space bar there are many, such as jump, attack or pause.

6. Alt Space key. This set of shortcut keys (Acer Aspire 1640Z Keyboard) will open the program the top left corner of the menu, which generally have the "Restore" "mobile," "size" "Minimize" "Maximize" and "off" a few options. This group then press the shortcut key, click "n" or "x" or "c" will be able to quickly minimize or maximize or close the window.

Routine maintenance of the keyboard

Keyboard and mouse, as is the entire computer in the cheapest parts, but that does not mean that there is no keyboard, the value of careful maintenance. If you use a keyboard properly maintained better, can be used a few years, on the contrary some of them even are not take a month. About the use and maintenance of the keyboard, not a particularly complex process, just a little in the course of our attention, you can play very good results.

1. Handling Gateway NV-48 Keyboard, you should cut off the power. Often seen in the PC market such a thing, businesses for the easy way, you hot plug the keyboard, in fact, this is very dangerous, easy to burn out the circuit board. So when you plug the keyboard must first shut down.

2. Dust on the keyboard regularly, but be careful not to let the water flow into the keyboard. When you use a clean damp cloth, dust free vacuum cleaner or compressed air to remove. If necessary, pull the keycap keys, as follows: off; selected to remove the key, with a small screwdriver to gently pry careful not to damage the other key; If you remove more than one key, to remember location of recovery. You can then key groove surrounding dust, to scraps of paper, hair, attention must not allow dirt or liquid fall into the keyway.

3. If you accidentally poured water on Gateway NV-48 Keyboard, then immediately do the following treatment:

(1) Immediately remove the keyboard, do not hesitate!

(2) With the mouse off.

(3) Turned over the keyboard, try to flush out the liquid.

(4) Use a hair dryer or fan blowing against the surface of the keyboard, attention must take hair dryer set to cold - do not bake the keyboard, just to dry.

(5) Allows the keyboard to place 12 hours, preferably in the sun to dry.

(6) Reconnect the power and start the machine.

4. Keep Gateway M-63 Keyboard clean surface. If there is dirt on the keyboard, it should be promptly removed. When not in use, can cover covering keyboard to prevent dust and waterproof.

5. Keyboard, do not use excessive force. Typing and playing games, due to excessive excitement, the intensity of keystrokes was too large, it is easy to cause the failure of the keyboard keys. Currently, there are a lot of the popular game software, game software requires a lot of heavy typing on the keyboard, the user should play or not play this little game, care to use the keyboard.

6. The above method is only effective water, other liquids if the case down on Gateway M-63 Keyboard, it had "symptomatic treatment", and that the principle of the use of immiscible liquid removed.

Design of the keyboard keys

Design concept

A keyboard keys design consists of two concepts, one of the main keys in English and digital design, the second is the design of sub keys.

 The most common English design and digital keys is commonly known as the "QWERTY" keyboard Curti. This is Christ the computer keyboard opher Latham Sholes invented in 1868 the program keys.

 As we all know, many articles in the main keyboard, said Curtis is designed to make typing speed not to fast. However, in these articles say there is a small error, which is - Curtis keyboard keys not designed to "make the keystrokes to the fast pace does not lead to stuck," but "not to card live under the premise of maximizing the typing speed. "

 Both say there is a subtle difference, that is, slow down typing speed is not the ultimate goal, QWERTY keyboard, not in blindly to reduce speed, it does have such a common combination of the ED in a slow down on the finger design, but there are many combinations, such as ER such accelerated keys.

 In fact the root cause of this design is that the structure of mechanical typewriters, and its lead character determines the structure of leverage when the two positions close to the lead character at the same time will be stuck when pressed, but relatively far away from the lead character of the two is not The same problem occurs, I believe there have been English typewriter should be able to use experienced people have experience.

 In Curtis keyboard, some commonly used letters are placed in the ring finger, little finger and other locations, this is considered to use the little finger to the other of inflexibility to reduce speed, but this argument does not take into account the actual situation of mechanical typewriters, While the index finger is the most flexible, but the index finger keys on the keyboard is the most likely stuck, so frequently used letters on the edge in order to ensure high-speed typing is not stuck is granted.

 Therefore, the ultimate goal of the design Curti keyboard is not to simply reduce the typing speed, in fact, Curtis is precisely the design of the keyboard to improve typing speed, but is "not stuck in the case try to improve the typing the speed. "

 The 20th century, the invention makes electromechanical typewriter typewriter typeface mechanical arm stuck no longer an important issue, many high-speed typing keyboard also emerged. The most famous is the DVORAK Dvorak keyboard.

 August Dvorak Dvorak keyboard was designed in 1930, Professor keys program, due to the mechanical structure is no longer considered key issues, so the keys arranged in full accordance with the idealized rate distribution design keystrokes. Finger movement stroke Bike Di keyboard is much smaller, the average typing speed almost doubled. But like many things, force of habit is hard to resist the Dvorak keyboard has only a very small number of professional occasions. But for people who want to try, where you can try Windows program comes with Dvorak keyboard.

Non-English keyboard

Basically all languages ??are English keyboard, keyboard, based on the changes made, most of the keys of the keyboard arrangement and English are not far, only a few subtle differences, such as the British dollar sign on the keyboard into pounds symbols, while the picture on the German keyboard swap the Y and Z position.

 Of the Far East in the English language Lenovo 3000 Keyboard with the key part of the standard U.S. English keyboard does not much different, but in some of the subsidiary on the key difference is obvious. For Chinese users, the most likely to see non-US language keyboard on the secondary market may be a common Japanese keyboard, and compared with the standard English keyboard, most of its keys are the same, but in some punctuation there are significant differences on the location, resulting in the English system occur when using some punctuation keys corresponding to the identity of the actual content and not on the situation. Another key bit design concept is the design of subsidiary keys, from the earliest IBM PC 83 keyboard, 108 key to the present mainstream Windows98 keyboard, has been updated several generations, but in general there is no fundamental change. Although there are some, such as compact design, but the market reaction was unsuccessful. Thus, the current design of the keyboard keys after many years of practice, the ideal is very mature design.

Cross keys

The so-called cross arrow keys, refers to the independence of the arrow keys on the keyboard were arranged in a cross, which was originally designed in the image closer to the 83 traditional keyboard design, but the actual effect is quite poor.

 The first is Microsoft's first generation cross key ergonomic keyboard use, but then it became this generation has been criticized, on the most famous design, cruciform keys look good, but what you will find that the actual use kinds of awkward button design will squeeze your fingers together, both in daily use or in the game are very inconvenient, especially in the racing game is almost impossible to play down. Therefore, the second generation of Microsoft products since they changed back to the original design.

 But irony is that Microsoft themselves have been the initiator of the arrow keys do not cross, but some recent domestic manufacturers but to pick up this self-defeating design back, but also as one of features designed to hype. Strongly suggest that you have not considered, or have bought enough subject.

Edit this paragraph keyboard structure

Earlier, we mentioned that, and now the keyboard is not really a true capacitor keyboard, so now what kind of keyboard is it? Let us open a keyboard to take a look. We can see from the pictures, a common ultra-thin keyboard, open the back of the screw after the keyboard can be split into several parts as shown in Figure.

 The first is on the cover and insert IBM Thinkpad T23 Keyboard and each key in which the Cap, which is the main contact with the user part. In the cover below, is a rubber membrane, the location of each key has a flexible Cap, this component is the main elastic components keyboard, a keyboard feel is the main character of this part of the decision and the materials, Therefore, the shape design and rubber components are the major keyboard manufacturers confidential. It should be noted that not all manufacturers use this integrated rubber membrane, some manufacturers such as BenQ in some keyboard keys are used to separate each of the rubber spring, so that each design is more conducive to maintaining keys feel unified, but more complex production processes.

 Following in the rubber membrane is three overlapping plastic film, covered with a thin film conductor layers from top to bottom, in the location of each key has two contacts, while the middle is a plastic film does not contain any wires, two separate upper and lower conductive film insulation off, and in the key position of the contact hole is opened.

 Thus, in normal circumstances, the upper and lower conductive film is the middle layer separated, will not turn on. However, after the pressure in the upper film, the site will be in the hole together with the underlying membrane, resulting in a key signal.

 Thus, now the keyboard is actually a touch-type keyboard, despite the very different shape, but in fact its basic principles and mechanical contact-style keyboard is the same, relying on mechanical contact with the conductive to generate the key signal. Is not a capacitive keyboard.

 The real name of this keyboard is actually called "membrane-contact keyboard", is a mechanical-contact keyboard. It is the same keyboard and mechanical contact, there is fragile and short life span problem, but the rubber springs instead of a metal spring, so it's touch keyboard is better than the mechanical contact and close to the capacitive keyboard, but life was not as capacitive keyboard, but the keyboard than the mechanical contact is much longer.

 The real Keyboard is based on capacitive non-contact capacitive conductive trigger principle, therefore, the circuit structure than the film-contact keyboard is much more complex, and the capacitive keyboard, each key is used in a closed structure, the overall cost is far much higher than the open-membrane contact keypad. So now in addition to a few high-end specialty other than the keyboard, in fact, has no real capacitive keyboard sold.

 In addition to the current mainstream films touch IBM Thinkpad T61 Keyboard, there is another "touch keyboard conductive rubber," which is characterized by only a layer of conductive film, in every key position has not connected the two contacts, and the lower rubber spring conductive rubber is used to produce, when pressed, when the two contacts will be connected.

 Can be seen, this calculator button keyboard principles and the principle is very close. In fact as early as the early personal computer, this design often in some ultra-thin laptop computers. Contact with the membrane keyboard is compared to a shorter life span of this structure, so now than in some other special purpose, has been gradually disappearing. In the upper right corner of the keyboard, there is a circuit with the film together with the board, this board is the core of the keyboard, coming from the conductive film will guide traffic through the wires enter the number into the circuit board computing chip, this chip will According to the upper and lower surface of the wires number two chip of a button through the arrangement of the table to find out the ASCII code corresponding to the button, through the interface to its output.

 This look-up table to obtain key coding approach called "non-coding-style keyboard," a relative of "coded keyboard", this keyboard is the ASCII code of each key directly from the digital circuit. Compared with the non-coding-style keyboard, the high cost of coding style keyboard, redefining problems, so it is very rare. Capacitive keyboard because it works, mostly coding style keyboard, which is another way that the mainstream now keyboard is not capacitive IBM Thinkpad T60 Keyboard.
